There is no "pstopdf" filter, so CUPS cannot convert the other types
of files into a printable format.

Either add a pstopdf filter script (probably using Ghostscript)
and register it using a /etc/cups/local.convs file, or add second
cupsFilter attribute to the PPD for application/vnd.cups-postscript
(use "-" as the filter if the printer is PostScript)
